Menacing Marcelo,

Attached patch exports scheduling policy and real-time priority from
/proc/<pid>/stats.

This code is in 2.4-ac and 2.5.

This does _not_ break previous versions of procps -- there is no harm
and it is fully backward compatible. New versions, starting with 2.0.8,
can parse this information.

Patch is against 2.4.20-pre9. Please, apply.
